AUTOMATIC OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 307,891, dated November 11, 1884.

Application filed September 13, 1884.

T aZZ whom it may concern.-

Be it known that I, JosEPH HANDFORTH TILKINSON, a citizen of the United States,

residing at Boston, in the county of Sufi'olk and State of Massachusetts, have invented certain new and useful Improvements in Automatic Oil-Cups; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My present invention relates to improvements in a class of automatic oil-cups containing provision for enabling the oil as it leaves the reservoir to be readily visible in order that the proper operation of the device may be insured. A notable instance of this class of oil-cups is shown in Letters Patent of the United States issued to myself on the 28th day of May, 1872, No. 127,205, in which the oilcup is adapted to supplylubricant to a crank, and is supported upon a frame suspended above such crank, the cup being screwed to the frame by a yoke which permits the escaping oil to be visible, while the oil drops upon and is arrested by a band of cloth or other porous material, which is disposed below the oil cup and stretched tightly from suitable supports making part of or secured to the lower part of the yoke before named, the tension ofthe porous bandbeinginsured by springpressure. To the top of the crank-strap is secured a cup which is open at top, and in the mouth of which is fixed a scraper, which at each revolution of the crank wipes against the band and scrapes from the latter a given quantity of oil,which descends into the cup, and from thence to the crank-pin.

The object of my present invention is to provide means for adapting the oil-reservoir and porous belt to the position of the crank in instances where an overhead support is not practicable; and to this end I employ a device, as hereinafter described, whereby said oil-reservoir and band are susceptible of freedom of motion and adjustment in vertical and horizontal directions, in lieu of being suspended immovable above the crank,'as shown in my said patent.

(No model.)

I In the accompanying drawings I have represented my invention as adapted to the requirements of an ordinary horizontal steam-engine, though I do not in any sense restrict it to this class of engine. In said drawings, Figure 1 represents a side elevation of my improved devices; Fig. 2, an end elevation of my improved device. Fig. 3 represents a vertical section of Fig. 2, the crank being removed.

A represents an upright column or pedestal erected upon or alongside of the pillarpost a of a steanrengine, while sliding vertically within this pedestal A is a rod or bar, 13, secured in position within the pedestal and at any desired height with respect thereto by a setscrew, 0, or other device. The upper part of the bar B extends above the top of-the pedestal A and supports a horizontal bar, D, which extends through it, the top of B being preferably enlarged into a head, 0, to provide a firm bearing for the said bar D. Upon the inner extremity of the bar or support D I secure the oil-reservoir, and as this oil-reservoir is constructed in manner similar to that shown in my said patent, I shall not describe its construction further than to say that its cup for containing oil is shown at H and its porous band at J. The porous or absorbent band J is covered with a hood, 6, to prevent settling or lodgment upon it of dust or other foreign matters. The connecting-rod of the engine is shown at (l, and the oil-cup secured to the same at L. As the bar B is adjustable within the pedestal A, it enables the height of the oil reservoir to be varied to suit the length of the crank, while the horizontal adjustment of the bar D, which is clamped by screw 0 in any position of such adjustment, enables the position of said reservoir to be varied to suit the position of the crank laterally of the pedestal. 1

By means of the above-described construction I do away with the overhead-support, which practically has proved to be, in most cases, awkward and impracticable, and I proa support for both of said devices, and ascrew l oil cup and porous band supported on rod D for adjusting said support, cup, and band hori and movable therewith, and the screw 0, which zontally. clamps the latter rod in any position to which 2. An automatic oil-cup and the porous l it may be adjusted horizontally. 5 band supplied thereby, in combination with In testimony whereof I affix my signature 1 asupport for-said cup and band, and screws in presence of two witnesses. I for adjusting them horizontally and vertically. JOSEPH IIANDFORTII WILKINSON.
